EPDM
Keltan® KSA 6405H
Crystalline ethylene-propylene rubber with medium ENB (ethylidene norbornene) content and a medium Mooney viscosity.
Due to its polymer structure this grade is extremely suitable for general purpose extrusion applications. The medium Mooney viscosity in combination with the medium molecular weight distribution ensures fast extrusion rates, whereas the medium ENB content ensures fast vulcanization. Last but not the least, the higher ethylene content enables higher filling degrees in combination with smooth profile surfaces.
This grade is very suitable for continuous extrusion applications (sealing systems, hoses and low voltage wire & cable) and molded goods.
